It looks like my cuttings have rooted successfully. Here's a picture of them today. In back (L-R) are Celadine and "mystery", in front are India and Grove Farm. The free "mystery" cutting has been the slowest to get started, which is not surprising since it was a bit desiccated when I got it. I'm very impressed with the quality from MPG and I'm going to give them a positive rating in Garden Watchdog (if these drop dead now it's my fault).

I don't think these will need repotting until next spring. How big should the leaves get before I start to feed them? I plan to start with 1/2 strength fertilizer at first.
